SPECIFICATION forming part 0f Letters Patent No. 671,103, dated April 2,1901.

Application iiled December 13, 1900. Serial No. 39,660. (No model.) I

To all 1071/0111, it may concern/.-

Beit known that I, JOHN W. D. CARSLAW, a subject of the Queen of GreatBritain, and

a resident of Chicago,- in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Tires forVehicle-Vheels; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters fof reference marked thereon,which form a part of this specification. 1

This invention relates to improvements in` tires for vehicle-wheels, andis shown more particularly in relation to a carriage-wheel.

Heretofore in devices of this class difficulty has been found insecuring the cushion-strip of the tire to the wheel, it being a commoneX- perience that such cushion-strips frequently roll from thechannel-retaining strip owing to the defective fastening devices.

The object of this invention is to provide simple and effective meansfor retaining the cushion-strip at all times in operative position.

The invention consists of the matters hereinafter described, and morefully pointed out and defined in the appended claims.

In the drawings, Figures l and 2 are Sections of a tire embodying myinvention. Fig. 3 is a fragmentary elevation of the same. Fig. 4 is alongitudinal section through the cushion-strip.

In said drawings my improved tire is shown in connection with the rim Aof a vehiclewheel of any desired kind, on the periphery of which issecured a channel-iron tire or rim B, provided with outwardly-directedslightlyflaring ianges b b. C indicates a cushionstrip, of rubber orother resilient material, of suoli shape at its base and of sufcientsize to fit closely within said channel iron or rim B. Said stripconsists of a central rounded portion adapted to form the tread of thewheel and provided on each side with shoulderscc of the same height asthe flanges b b on the channel-iron B. y

D indicates a rod `or wire of metal bedded in the cushion-strip C,centrally near the base of the same, and which when the cushionstrip isin position-in the channel of the rim is drawn together and the endspermanently united, thereby acting as one of the retaining means. Aplurality of relatively short rods or wires d d are also bedded in thecushionstrip and extend from opposite sides of the saine at points belowthe shoulders c o to points below and beyond the rod or wire D, asindicated in Figs. l, 2, and et. Said rods or wires d d are arrangedstaggering on opposite sides of the cushion-strip and preferably but ashort distance apart, and incline centrally and downwardly at. the innerends until but a relatively thin portion of the rubber is between thesaine and the channel or rim when in place.

E F. indicate metallic bands or wires, as shown, provided with an'insulated coating. Said bands E E are passed over the flanges 'b b resectivel i and engage the shoulders D i c c c, acting to compress thebase of said cushion-strip into said channel-rim. Said bands may be ofany desired form, either cylindric in cross-section, as shown in Fig. 1,or semicircular in cross-section, as indicated in Fig. 2, in which,shown, the outer surface thereof is rounded and the inner surfacethereof flattened to afford better engagement with the shoulders c c.Obviously the rod D and the rods or wires (l d may be inserted in thecushion-strip before the same is vulcanized and may be entirelyconcealed within the same.

The operation of my device is as follows: The rim of the wheel beingprovided with the channel-strip B, as before described, the rub- `loertire C, of suitable size, is inserted within the channel-strip, asindicated, and the bands E E are sprung into position. Said bands areformed of a strip of wire or the like having the ends integrally joinedand made of slightly less diameter than the outer edge of the iianges bb and may be preferably secured on said shoulders by jumping them on.Obviously when in position said bands act to crowd said shoulders o cdownwardly between said flaring anges b b,- with the effect of crowdingthe rods d d inwardly beneath the rod D. Outward strain on saidcushion-strip is distributed equally over the entire base by means ofthe said rods d d and the rod D. Inasmuch, however, as the bands E and Edo IOO not engage the rods d there is no tendency of the rods to tearthe rubber, thereby shorten ing the life of the tire. Furthermore, byinsulating the bands E and E', as indicated in Fig. l, the said bandsare protected from moisture and from contact with the flanges Z9 Z) orthe rubber of the tire, thereby not only protecting from oxidizing, butas well protecting the rubber from the changes due to such oxidation orto electrical action owing to contact with the rim.

Obviously many changes may be made in the details of construction asherein shown and described without departing from the principle ofmy-invention- I claim as my inventionl. In a tire for vehicle-wheels incombination with the channel-strip adapted to be secured peripherally onthe vehicle-wheel of a cushion-strip adapted to fit closely within saidchannel-strip projecting' outwardly beyond the same, shoulders on eachside of said cushion strip approximately of the same height as theflanges on the channel-strip and provided withl rods or wires bedded insaid cushion-strip beneath said shoulders and extending from the outerside to a point below and beyond the center and an insulated band drawnabout each of said shoulders and acting to bind the cushion-strip withinsaid channel.

2. In a tire for vehicle-wheels the combination with achannel-stripadapted to be secured peripherally upon t-he rim of thewheel, of a cushion-strip fitting closely Within the channel andprojecting beyond ther same, shoulders on each side of saidcushion-strip approximately of the same height as the flanges on saidchannel-strip, a longitudinal wire or the like vbedded therein centrallyand approximately near its base and transverse rods or wires arrangedstaggering and extending from the outer side of the cushionstrip beneaththe shoulders to points below and beyond said longitudinal wire andmetallic bands drawn about said cushion-strip at the shoulders andacting to bind the same within the channel-strip.

points below and beyond said central bedded rod or wire and means forretaining the cushion-strip in position in said channel comprisingmetallic bands provided with an insulating-coating drawn tightly aboutsaid shoulders.

4. An article of manufacture for the purpose specified, comprising aresilient cushionstrip having a central part adapted to form atread-surface, shoulders on each side of said central tread-surface, alongitudinal wire or rod bedded centrally in said cushion-strip,approximately near the base and transverse rods or wires bedded in saidcushion-strip arranged staggering and extending from beneath saidshoulders to points below and beyond said longitudinal bedded rod orwire.

5. An article of manufacture for the purpose specied, comprising aresilient cushionstrip having a central part adapted to form atread-surface, shoulders on each side of said tread-surface, a centralaperture extending longitudinally through the cushion-strip, below thecenter and transverse rods or wires bedded in said cushion-striparranged staggering and extending from beneath said shoulders obliquelydownward to a point below and beyond said central aperture.

In witness whereof I have hereunto subscribed my name in the presence oftwo subscribing witnesses.
